Convert text to any case, instantly
Type or paste your text once and get it back in nine different cases at the same time: UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case and alternating case. It updates as you type, so you can fix a heading, tidy a variable name, or shout a message without retyping a thing. Everything is converted on your own device, so your text is never uploaded.
How to convert your text
- Add your text. Type directly in the box, or paste it from anywhere.
- Pick the case you want. Every format is shown at once and updates live.
- Copy it. Use the copy button next to any result, then paste it wherever you need.
The case formats explained
- UPPERCASE makes every letter a capital: HELLO WORLD.
- lowercase makes every letter small: hello world.
- Title Case capitalises the first letter of each word: Hello World.
- Sentence case capitalises the first letter of each sentence: Hello world. How are you.
- camelCase joins the words and capitalises each one except the first: helloWorld. Common for variables in code.
- PascalCase joins the words and capitalises every one: HelloWorld. Common for class names.
- snake_case lowercases the words and joins them with underscores: hello_world.
- kebab-case lowercases the words and joins them with hyphens: hello-world. Common for URLs and CSS.
- alternating case flips between lower and upper on each letter: hElLo wOrLd.
Frequently asked questions
Is my text sent anywhere?
No. Every conversion runs in your browser with plain JavaScript. Your text is never uploaded or stored on a server, which keeps it completely private.
What is the difference between camelCase and PascalCase?
Both join the words together with no spaces. camelCase leaves the first word lowercase (helloWorld), while PascalCase capitalises every word including the first (HelloWorld).
Does it keep my line breaks?
UPPERCASE, lowercase, Title Case, Sentence case and alternating case keep your line breaks and spacing. The programmer formats (camelCase, PascalCase, snake_case and kebab-case) join everything into a single token, since that is how those styles are used.
Can I convert a whole paragraph at once?
Yes. Paste as much text as you like. The tool converts all of it instantly and you can copy any format with one click.
Is it really free?
Yes, it is free with no sign-up, no watermark, and no limits.
